Does Optalert record my data and what does it do with it?

Optalert records and stores information about when warnings were given and what the driver’s drowsiness score was each minute over the last few hours of driving. What this recorded data is used for will be decided by individual drivers and their managers, not by Optalert Pty Ltd. The system also stores the last few operational hours of "raw" data about individual eye and eyelid movements which can be downloaded from the vehicle. This data is of no practical value except for research purposes.
